Definitions

  • the invention concerns a lobster house or lobster habitat in water resistant materials consisting of one or more elements equipped with recesses of varying sizes of opening and depth, which can be through-going in the element, wherein the element is composed of a block of uniform thickness or a block which is thicker at one end.
  • Lobsters are a stationary crustacean. However, they are cannibalistic and dependent on natural hiding-places in order to attain full growth. These hiding-places must provide adequate protection while at the same time giving access to volumes of water which are regularly replaced, thus providing satisfactory supplies of food.
  • the hiding-places may, e.g., be hollows or recesses in soft species of rock, coral reefs or loose stones. These rocks will be capable of providing overhang and hiding-places while at the same time the current of water supplies food. The result of this therefore is that there are large areas along the coast which are not suitable for lobsters even though the food supply may be adequate.
  • the lobster habitat On the basis of the above information, it is important for the lobster habitat to consist of one or more large surfaces with recesses perpendicular to the surface, with varying depth and shape of the openings which must be of different sizes in order to give shelter to the lobsters at various stages of their growth and where this lobster habitat can be designed in such a manner that the surfaces are exposed to replacement of the volumes of water.
  • the structure should be simple to deploy on the seabed with existing maritime technology and once it has been deployed it should be capable of establishing a stable structure on the seabed with is not moved by the currents.
  • the present invention is therefore composed of one or more elements of water resistant material wherein the element consists of a block of uniform or varying thickness provided with holes on both of the two largest opposite surfaces, the main surfaces, of the same or different depths or through-going holes, in which the circumference of the holes on the element's main surfaces may have any suitable shape and different sizes. Since the elements have to be placed preferably on their edges on the seabed, they can be designed with the greatest thickness at the end which is intended to form the base, thus concentrating most of the weight here, while at the same time the holes on each side of the thicker part can be deeper than the holes which are formed in the blocks higher up towards what will constitute the top of the element when it is deployed.
  • FIG. 1 is a perspective view of a lobster habitat element 1 according to the invention with recesses 2 which have larger openings and are deeper towards the base of the element which is also thicker at this end.
  • FIG. 2 is a plan view of one of the surfaces of the element in which the openings 2 in the opposite plane are illustrated displaced in relation to the plane's openings.
  • One set of openings 3 is through-going
  • FIG. 3 is a section through line III--III in FIG. 2 and demonstrates that the recesses nearest the base are deeper than those higher up, a through-going row of holes 3, in addition to which the trapezoidal appearance of the cross section is demonstrated.
  • FIG. 4 illustrates an embodiment of the invention in which three elements are connected together in the form of a star in which the base of each element is thicker than the top of the element. Hole 4 indicates lifting arrangements which are used when deploying the structure.
  • FIG. 5 illustrates the structure as in FIG. 4, but here the elements are cast individually and connected together by means of a bottom plate 5, top bracket 6 and safety bolt 7.
  • FIG. 6 illustrates an embodiment of the invention wherein the elements which in this case are of uniform thickness are connected in order to form a mooring.
  • the individual element according to the invention can be in the form of a block 1 (FIG. 1) of water resistant material with two opposite surfaces, the main surfaces, 8,9, where the block is thickest at the end which will be the base when it is placed on its edge, the cross section of the two main surfaces thus having a trapezoidal shape (FIG. 3).
  • This shape permits deeper holes 2 to be placed at the base while at the same time stabilizing the element on the seabed, since the base becomes heavier than the top.
  • Each of the main surfaces 8,9 is provided with openings 2,3 of any shape and size whatever and with recesses inside the element, or recesses 3 which pass right through the element. These are, e.g., arranged in rows (FIGS. 1,2), but can also be randomly arranged over the whole element in such a manner that the largest openings with the deepest recesses are located in the element's thickest end (FIG. 3).
  • the different sizes of the holes mean that they can house lobsters of different sizes, and at different stages of development.
  • the element or plate has uniform thickness with holes 2,3 of varying shape and depth on both surfaces, displaced in relation to each other in the same way as that illustrated in FIGS. 1-3. This embodiment of the element is not illustrated.
  • the elements are made of a heavy, water resistant material, e.g. concrete.
  • a heavy, water resistant material e.g. concrete.
  • Experience has been built up over a long period of time with concrete structures in water, such as salt water.
  • concrete structures in water, such as salt water.
  • concrete is advantageous since;
  • the material on the surface consists of Si and Ca ions which are the main component of natural bottom materials
  • the upper part can be cast in light aggregate concrete.
  • the use of a combination of light aggregate concrete at the top and normal concrete towards the base provides an optimum construction since it gives maximum marine growth, the weight is reduced and the stability is ensured.
  • a structure in which the weight is low enough for deployment to be undertaken without problems, and the surfaces exposed to the surrounding water are large in relation to the volume of the structure is illustrated by the embodiments in FIG. 4 and FIG. 5.
  • a star-shaped structure of this kind can comprise from 3-6 individual elements, preferably 3. Such a shape will provide turbulence in the water in movement and help to ensure that the turbulent volumes of water carry food with them and supply this food to all the openings in the exposed surfaces.
  • FIG. 4 The design according to the invention illustrated in FIG. 4 is cast as a whole and requires larger transport and crane equipment.
  • FIG. 5 a design is illustrated where the individual elements are driven up to the wharf and connected together on a bottom plate 5 with top bracket 6 and safety bolt 7.
  • the bottom plate 5, top bracket 6 and safety bolt 7 can be made of any suitable material which is water resistant and which can withstand the stresses involved.
  • the elements or blocks, which are now of a uniform thickness, are assembled to form a mooring (FIG. 6) which combines great weight with the possibility of providing the right conditions for the growth of lobsters.
  • This structure will be constructed of normal concrete alone, or a combination of normal concrete and light aggregate concrete, with the latter in the top part of the mooring.
  • This design will be suitable for attaching to wharfs and buoys for use by private house and cabin owners while at the same time providing optimum conditions for the growth of marine organisms, such as crustacea.
